Description

Technical Field

[0001] The utility model relates to the field of water washing of dimethyl biphenyl ether, and specifically to a water washing kettle for filtering dimethyl biphenyl ether. Background Art

[0002] In the process of synthesizing dimethyl biphenyl ether, various impurities will be generated. Therefore, it is necessary to wash the crystalline powder of the synthesized dimethyl biphenyl ether with water. Currently, the commonly used water washing solution for dimethyl biphenyl ether is an alcohol solution. Then, a water washing kettle is used to wash dimethyl biphenyl ether. A stirring shaft and stirring blades are arranged inside the water washing kettle. The stirring blades stir the mixture of the water washing solution and dimethyl biphenyl ether, so that dimethyl biphenyl ether is dissolved in the alcohol solution. After the stirring is completed, the mixed solution is allowed to stand for a period of time, and then the upper layer solution of the mixed solution is pumped away, leaving the bottom layer solution of the mixed solution and the precipitate at the bottom. Since the boiling point of alcohol is only 78.3 degrees, the upper layer solution is distilled and separated to obtain a purer dimethyl biphenyl ether powder. In the above process of washing dimethyl biphenyl ether with water, the time consumed by the mixed solution of the alcohol solution and dimethyl biphenyl ether during standing is relatively long, resulting in low water washing efficiency and slow speed of dimethyl biphenyl ether, which is both time-consuming and laborious.

[0003] The Chinese utility model patent with the publication number CN 216295336 U discloses a water washing kettle for filtering dimethyl biphenyl ether, which relates to the field of water washing of dimethyl biphenyl ether. It includes a water washing tank, on which a feed pipe, a discharge pipe, a water inlet pipe and a water outlet pipe are provided. The top of the feed pipe is higher than the top of the water washing tank; a first filter screen is arranged on the inner wall of the water washing tank and divides the inside of the water washing tank into an upper chamber and a lower chamber. The feed pipe, the discharge pipe and the water inlet pipe are all communicated with the lower chamber of the water washing tank, and the water outlet pipe is communicated with the upper chamber of the water washing tank; a stirring shaft and a first stirring blade, one end of the stirring shaft is rotatably connected to the bottom of the water washing tank and the other end floats in the lower chamber of the water washing tank. The number of the first stirring blades is multiple and they are evenly distributed on the stirring shaft; and a power part is fixed to the bottom of the water washing tank, and the output end is connected to the stirring shaft to drive the stirring shaft to rotate. The water washing speed of dimethyl biphenyl ether is accelerated and the water washing efficiency of dimethyl biphenyl ether is improved.

[0004] The above-mentioned published literature does not have a structure for cleaning attachments and reaction impurities, so that the inner cavity of the water washing kettle as a carrier will gradually be attached by attachments.

[0027] Even further, a feeding port 9 is installed through the front side of the upper surface of the cover 8, and a reaction solution delivery port 10 is installed through the rear side of the upper surface of the cover 8. The installed feeding port 9 enables the liquid containing diphenyl dimethyl ether to be continuously injected, and the reaction solution delivery port 10 can send in the reaction solution for diphenyl dimethyl ether, suitable for diphenyl dimethyl ether to quickly react to form flocculent substances.
